Who it fits

Key specs explained

Rated Power: 220W

This value indicates the maximum energy output the panel can generate under ideal conditions. You can use this number to estimate how quickly it charges your portable power station. Higher wattage generally means faster charging for devices like camping fridges or emergency backup systems. Compare this rating against the input limits of your power station to ensure compatibility and optimal performance during outdoor trips.

Conversion Efficiency: up to 23.5%

This percentage shows how much sunlight the panel converts into usable electricity. A higher efficiency rate means you get more power from the same amount of sun. This is particularly useful if you have limited roof space or need to maximize energy capture during short daylight hours. When shopping, compare this figure with other panels to gauge which model offers better performance per square foot.

Panel Type: Bifacial, Foldable

Bifacial technology allows the panel to capture sunlight from both the front and the back, using reflected light from surfaces like snow or sand. This design can increase overall power generation by up to 30%. The foldable feature makes it easy to transport and store in your vehicle. Look for this combination if you need versatile, space-saving gear for camping or RV travel.

IP Rating: IP68

This rating confirms the panel is dust-tight and protected against continuous immersion in water. You can rely on it for heavy rain or accidental spills without damaging the internal components. This durability is essential for outdoor enthusiasts who face unpredictable weather. When comparing options, check the IP rating to ensure the panel can withstand the specific environmental conditions of your intended use.

System Voltage: 20V

This voltage level indicates the electrical output required to connect with compatible power stations. You must ensure your portable power station supports a 20V input to use this panel effectively. Mismatched voltage can prevent charging or damage equipment. Always verify this specification against your power station’s input requirements before purchasing to guarantee seamless integration and safe operation.

Design and build details

The listing describes a black panel with a robust anti-corrosive aluminum frame. This metal construction provides thermal stability and helps the unit withstand outdoor conditions. The surface features an ETFE coating, which the manufacturer states enhances dust resistance and weatherproofing. You should rely on this coating to protect the cells during extended camping trips or RV use.

The panel weighs 11 lbs and folds to dimensions of 26.7 by 34.6 inches with a thickness of 1.3 inches. It includes two kickstands that allow for three angle adjustments: 40, 50, and 60 degrees. This layout helps you maximize sunlight exposure on flat surfaces. The built-in accessory pouch keeps your cables organized when you are not generating power. According to the listing, the IP68 waterproof rating ensures the panel can endure rain and moisture, making it suitable for unpredictable weather.

You will find a 7-in-1 solar cable included in the box. This cable connects via DC8020, DC7909, DC35135, XT-60, or Anderson connectors. This variety allows you to link the panel to different power stations without needing extra adapters. The bifacial design captures direct light from the front and reflected light from the back. You can place the panel on snow, sand, or white roofs to boost energy production by 10 to 30 percent compared to single-sided panels.

Setup and everyday use guide

Setting up this E-POWO panel involves unfolding the unit and deploying its two built-in kickstands. You can adjust the angle to 40, 50, or 60 degrees to maximize sunlight capture. The foldable design allows it to compact down to 26.7 by 34.6 inches, making it easy to store in your gear. The included accessory pouch helps keep small parts organized during transport. For connectivity, the package includes a 7-in-1 solar cable. This cable features multiple connectors, including DC8020, DC7909, DC35135, XT-60, and Anderson plugs. This variety ensures compatibility with a wide range of portable power stations. You must ensure your power station supports a 20V input for proper operation. The bifacial design requires you to position the panel on a reflective surface, such as snow, sand, or a white roof. This placement allows the back side to capture reflected light, potentially increasing power generation by 10 to 30 percent compared to single-sided panels. The IP68 waterproof rating and ETFE coating mean you can leave it outdoors in various weather conditions without immediate concern for damage. The anti-corrosive aluminum frame adds stability, helping the panel remain secure in strong winds. Daily use is straightforward: unfold, angle, connect, and charge. The 11-pound weight makes it manageable for most users to carry during camping trips or RV travel. Always keep the panel clear of obstacles to maintain optimal efficiency.

Before You Buy This Solar Panel

You need to verify your power station accepts a 20V input before purchasing. This panel is designed for high-capacity units, so compatibility is critical. The included 7-in-1 cable supports DC8020, DC7909, DC35135, XT-60, and Anderson connectors. If your device uses a different port, you may need an adapter. The IP68 rating means it resists water and dust, but you should still wipe down the ETFE-coated surface after use in sandy or muddy conditions to maintain its 23.5% conversion efficiency. Keep the kickstands clear of debris to ensure stable placement at 40, 50, or 60 degrees. This unit weighs 11 lbs, making it lighter than many rigid panels in the 1 options available. It fits well for RV trips or camping where weight matters. Ensure you have a flat surface for optimal bifacial light capture from the back. Proper storage in its pouch extends the lifespan of the monocrystalline cells.

Check before you buy

• Confirm your power station supports 20V input voltage.
• Check if included 7-in-1 connectors match your device ports.
• Ensure you have a flat surface for kickstand placement.
• Verify the IP68 rating meets your weather exposure needs.
